Forecast Explanation

This forecast is produced by a multi-model ensemble consisting of dynamical atmospheric models,
which are forced by the latest observed atmosphere, ocean, land and ice conditions. The models
are designed to simulate features of the real atmosphere, including the daily movement of long
and short wave patterns in the Southern Hemisphere.

The future probability of rain in each district is estimated using output from the multi-model
ensemble, combined with historical information about the difference between the model forecasts
and observed rainfall.

In this deterministic framework the skill of the forecast tends to decrease with time, however
the forecasts are updated daily to provide the latest estimates of rainfall probability out to
28 days.

It was an aptly named Sunday today, with temperatures reaching 28 degrees in the city, and hitting 30 degrees for western Sydney.
A very weak seabreeze and increasing cloud will keep the temperatures up overnight, with the eastern suburbs looking to only drop to 16-to-18 degrees overnight.
On Monday, it will be another warm one.
